The thermal conductance of a two-channel Kondo model
C. P. Moca, A. Roman, D. C. Marinescu
A theory of thermal transport in a two-channel Kondo system, such as the one formed by a small quantum dot coupled to two leads and to a larger dot, is formulated. The interplay of…
Spin-Hall Effect in A Symmetric Quantum Wells by A Random Rashba Field
C. P. Moca, D. C. Marinescu, S. Filip
Changes dopant ion concentrations in the sides of a symmetric quantum well are known to create a random Rashba-type spin-orbit coupling. Here we demonstrate that, as a consequence,…
Density matrix numerical renormalization group for non-Abelian symmetries
A. I. Toth, C. P. Moca, O. Legeza +1
We generalize the spectral sum rule preserving density matrix numerical renormalization group (DM-NRG) method in such a way that it can make use of an arbitrary number of not neces…
Finite-size Effects in a Two-Dimensional Electron Gas with Rashba Spin-Orbit Interaction
C. P. Moca, D. C. Marinescu
Within the Kubo formalism, we estimate the spin-Hall conductivity in a two-dimensional electron gas with Rashba spin-orbit interaction and study its variation as a function of diso…
Longitudinal and spin-Hall conductance of a two-dimensional Rashba system with arbitrary disorder
Catalin Pascu Moca, D. C. Marinescu
We calculate the longitudinal and spin-Hall conductances in four-lead bridges with Rashba - Dresselhaus spin-orbit interactions. Numerical results are obtained both within Landauer…
